Comment 4 for bug 767332

Good point Martin. I've pushed the version where renames are used for hiding, but I'm interested if there would be interest in a sort of advisory field for the status of a branch. Now that we have "bzr config", there is an easy way to change that sort of metadata from the UI, so it wouldn't have to be special-cased for bzr-colo. I will ask on the list if there are other parts of the Bazaar ecosystem that would be interested in using a branch_status flag.
